Digestive Enzymes and Stomach Acid: When Can Delayed Release Matter?

People filling digestive enzyme powders often ask whether a normal capsule is enough or whether delayed release is preferable. The answer depends on the enzyme and the intended formulation.

Are digestive enzymes affected by stomach conditions?

Different enzymes have different stability and activity profiles. Acidic conditions can affect some enzymes more than others, while other enzymes are intended to work under acidic conditions. This is why the specific ingredient matters.

What does a delayed-release capsule do?

A delayed-release capsule is designed to postpone opening compared with a conventional capsule under gastric conditions. It does not make every enzyme more effective, and it does not replace formulation-specific stability data.

Standard HPMC vs DRcaps®

Standard HPMC capsules are widely used for dry powders and open normally after swallowing. DRcaps® delayed-release capsules are HPMC capsules designed for delayed release and may be considered when the formulation benefits from avoiding immediate release in the stomach.

Which enzymes might need special consideration?

Proteases, lipases, lactase and other digestive enzymes differ in their preferred conditions. Always check the specifications for the particular enzyme rather than applying one rule to all enzyme products.

Choosing an empty capsule

Consider the ingredient, powder density, required dose, capsule size and whether delayed release is actually needed. DRcaps® are intended for dry fills and should not be treated as liquid-filled capsules.

Shop compatible empty shells: Browse DRcaps® sizes 000–4 for suitable dry powder fills, or see Size 000 clear DRcaps®. Check the ingredient and formulation requirements before choosing a shell.

Important: If the enzyme product is prescribed or supplied in a specific dosage form, consult a pharmacist or healthcare professional before changing how it is taken.

I've been using DR caps from pure capsules for a few years

I have been using the clear DR capsules from pure capsules for three years now. Like many others leaving reviews, I have a chronic UTI and I'm on hiprex and long term antibiotics. In order to protect my stomach I encapsulate all of these drugs in a 000 capsule which fits hiprex and coamoxiclav. The service that Bob and his team gives is first class. Quick to answer emails and the capsules are sent out very quickly.

Would highly recommend this Company and their delayed release capsules if you're on long term medication that affects your stomach. My symptoms are much improved and the staff couldn't be more friendly and helpful when processing orders. A truly professional service. Thank you.

This company is amazing

This company is amazing. They have acid resistant capsules, which I can put my medication in, and have literally been a life-saver. They are reasonably priced, available to purchase as a individual customer (instead of just being for businesses), and the capsules always arrive in good time. I have never had any issues with this company and highly recommend them.

God Send for cUTI long term medication

These have been a god send. My long term medication for CUTI (hiprex and antibiotics) are very difficult to take as harsh on the tummy causing nausea, burning, reflux etc. If i encapsulate them in the enteric coated capsules they don't release until they hit the small intestine so all them nasty side effected no longer happen. Without these i wouldn't be able to stay on my medication and be extremely unwell so I am very grateful these are available!
